Maintenance Kpi’S

  1. 2. <ul><li>1. Cost of managing processes </li></ul><ul><li>Periodic costs of managing processes, usually based on the number of Full Time Equivalents (FTEs) involved in management functions for processes </li></ul><ul><li>Formula: (Total cost for managing processes) divided by (period) </li></ul><ul><li>Unit type: Money </li></ul>
  2. 3. <ul><li>2. Mean Time to Repair (MTTR) </li></ul><ul><li>Average time (e.g. in hours) between the occurrence of an incident and its resolution. </li></ul><ul><li>Formula: Average of time between resolution of incident and start of incident </li></ul><ul><li>Unit type: Time Direction: Minimize Unit: Hours </li></ul>
  3. 4. <ul><li>3. % of service requests resolved within an agreed-upon period of time </li></ul><ul><li>Percentage of service requests resolved within an agreed-upon/acceptable period of time. </li></ul><ul><li>Formula: [Service request resolved within the agreed time] percentage of [Total service request] </li></ul><ul><li>Unit type: Percentage Direction: Maximize </li></ul>
  4. 5. <ul><li>4. Mean-time between failure (MTBF) </li></ul><ul><li>The average time between equipment failures over a given period i.e. the average time a device will function before failing. It is the reliability rating indicating the expected failure rate of equipment. </li></ul><ul><li>Interpretation: It is the reliability rating indicating the expected failure rate of equipment. </li></ul><ul><li>Unit type: Time Direction: Maximize Unit: Days </li></ul>
  5. 6. <ul><li>5.% of outage due to incidents (unplanned unavailability) </li></ul><ul><li>Percentage of outage (unavailability) due to incidents in the IT environment, relative to the service hours. </li></ul><ul><li>Unit type: Percentage Direction: Minimize </li></ul>
  6. 7. <ul><li>6. Availability (excluding planned downtime) </li></ul><ul><li>Percentage of actual uptime (in hours) of equipment relative to the total numbers of planned uptime (in hours). </li></ul><ul><li>Planned uptime = service hours – planned downtime </li></ul><ul><li>Planned downtime is downtime as scheduled for maintenance. </li></ul><ul><li>Also known as: Service Outage Duration </li></ul><ul><li>Formula: [Actual uptime] percentage of [Planned uptime] </li></ul><ul><li>Unit type: Percentage Direction: Maximize </li></ul>
  7. 8. <ul><li>7.% of outage due to changes (planned unavailability) </li></ul><ul><li>Percentage of outage (unavailability) due to implementation of planned changes, relative to the service hours. </li></ul><ul><li>Formula: [Outage due to planned changes] percentage of [total Outage] </li></ul><ul><li>Unit type: Percentage Direction: Minimize </li></ul>
  8. 9. <ul><li>8.Overall Equipment Effectiveness (OEE) </li></ul><ul><li>Overall Equipment Effectiveness (OEE) = Availability x Performance x Quality </li></ul><ul><li>Availability = Operating Time / Planned Production Time </li></ul><ul><li>Performance = Ideal Cycle Time / (Operating Time / Total Pieces) </li></ul><ul><li>or </li></ul><ul><li>Performance = (Total Pieces / Operating Time) / Ideal Run Rate </li></ul><ul><li>Quality = Good Pieces / Total Pieces </li></ul>
